Can't see a guide to convert to UK sizes e.g.14, 16, 18. What should a size 16 person order?

I am a size 10-12 what should I order. I like them snug but not too tight they are unconfortable. thank you.

what is the length of the inside leg. thank you.

If I wanted a size 12 would I go for Small or medium as there is not a size 12 to choose from. Thank you
